Physics Behind the ECG

The Limb Leads

Learn about the limb leads and their views of the heart

The limb leads are placed on all 4 limbs. Look at the diagram, this shows the actual point from which electrical activity is measured....

The Chest Leads

Learn about the chest leads and Wilson's central terminal

The chest leads work in the same way as the limb leads but give different views. 

Instead of looking at one lead to another their view is towards ....

 

The Augmented Leads

Learn about the formation of the augmented leads

We are studying the 12 lead ECG, however so far using the 10 leads that we have attached we only have 9 different views of the heart to look at....

 

 

 

 

Use this outline if you have no prior knowlege of ECGs, how they work or how to set them up. This map will take you through the basic physics and anatomy, set up of the ECG and will touch on interpretation. There is a test at the end to examine your understanding.

​

 

Use this outline if you have some prior knowlege of how an ECG works, its set up and a good understanding of the anatomy of the heart's conducting system. This will focus on interpreting the readings on different leads of the ECG.

 

​

 

Use this map if you already have a thourough understanding of heart anatomy, different arrythmias and their appearance on ECGs. This map focuses on testing your existing knowledge of interpreting ECGs.
